Résumé: The present paper introduces Scala-of-Coq, a new compiler that allows a Coq-based synthesis of Scala programs which are ``correct-by-construction’’. A typical workflow features a user implementing a Coq functional program, proving this program’s correctness with regards to its specification and making use of Scala-of-Coq to synthesize a Scala program that can seamlessly be integrated into an existing industrial Scala or Java application.
